GYMNAS'IIC APPARATUS.

Application filed August 20, 1921, Serial No. 493,987. Renewed June 16,1924.

To all whom it may concern.

Be it known that we, IRA R. NELSON and FREDERICK WV LAMBIE, citizens ofthe United States, residing at Minneapolis, in the county of Hennepinand State of Minnesota, have invented certain new and usefulImprovements in Gymnastic Apparatus, of which the following is aspecification.

This invention relates to gymnastic apparatuses for children and themain object is to provide a durable, practical and cheaply constructeddevice embodying a number of features adapted to be interchangeably andselectively used by the child using it. A

further object is to make" the device adjustablein such a manner thatthe child will by adjusting and interchanging the various parts develophis mind as well as his body. Still further objects will be disclosed inthe course of the following specification and are illustrated in theaccompanying drawings, in which:

Fig. 1 is a side elevation of the device, showing it as arranged forholding a teetering board.

Fig. 2 is an end elevation of the device, arranged for supporting aswing Fig. 3 is an end elevation of the device adjusted and arranged forthe use of the parallel bars.

Fig. at is a modified detail of the upper end of the vertical frame.

Fig. 5 is a sectional view on the line 55 in Fig. 1.

Fig. 6 is an enlarged detail section on the line 66 in Fig. 5.

Fig. 7 is an enlarged detail section on the line 77 in Fig. 1.

Referring to the drawings by reference characters 8 designates a pair oftransverse bars resting on the floor or ground and on which the deviceis mainly supported. Adjustably secured on the bars 8 is a pair ofparallelly arranged side frames, each consisting of a long base bar 9,two upright members 10, supported in vertical position by angular braces11 and 12, and a horizontal rail 13 secured on the tops of the members10. The braces 11 are secured by bolts 14 at their lower ends to theextreme ends of the base bars 9, and extend far enough therebelow (seeFigs. 1, 2 and 3) to rest on the ground, thus more firmly bracing the bemoved to the holes 16 (see Fig. 2) so that the rails 13 can be securedin closer relative positions (see Fig. 3). In this event secured bybolts having wing nuts 21 to the side frames, when the latter are'intheir outer positions, as shown in Figs. 1 and 2. Brackets 22, holdingthe members 19 and 20 together, are secured to the bar 20 by eye. bolts23 in which are secured the upper ends ofa pair of chains 23. Each chainconsists of an upper and a lowersection, being detachably connected byahook 24c. lVhen so connected aseat 25 is provided at the lower ends ofthe chain, and the device is then in readiness for use as a swing? asshown in Fig. 2. hen so desired the lowersections of the chains 23 andthe seat 25 are detached, leaving the upper chain section free to besecured, as shown in Fig. 4, to a pair of rings 26'. 'Two sets of cleats27, having receiving slots 28 (see Fig. 6), are secured on the innersides of the uprights 19. Around bar 28 is adapted to rest horizontallyin either of said sets of cleats, and when in the lower position isadapted to support and act as a fulcrum for a teeter board 29, thelatter having blocks 30 to prevent it from slipping. With the teeterboard 29 and chains 23 entirely removed the bar 28 may be inserted, inthe upper set of cleats, as suggested by dotted lines in Fig. 2, thusproviding a rigid turning pole, on which anumber of gymnastic feats maybe performed. A trapeze bar may also be provided by attaching a bar inthe lower ends of the upper chain sections,

or by inserting it in the rings 26.

the bolts 17 of the moved side frame must 7 With the high frame'removedand the side frames closed in, as shown in Fig. 3, the device provides aset of parallel bars or rails 13, on which also a large number ofexercises may be taken.

It will thus be obvious that a device of this construction will not onlyrequire but very little room, but will be portable and may be usedeither in a house or yard. Furthermore, its many adjustments andinterchangeable features will enable a child to amuse himself for hoursand at the same time provide exercises of almost any nature. 7

It is understood that suitable modifications may be made in the designand structure of this device, provided, however, that such modificationscome Within the spirit and scope oi the appended claims- Having nowtherefore fully shown and described our invention What We claim; to benew and desire to protect by United States Letters Patent is:

1. An apparatus of the class described comprising, a pair of transversebase men-rbers, side frames, secured't'o saidbasemembers, said sideframes having parallel bars at their upper ends averti'cal frame-securedto said side frameaand consisting of apair of uprights and a cross "beam"connecting their upper ends. V

2. An apparatus of the class described comprising, a pair of transversebase members, side frames, supported on "said base members, said sideframes having parallel bars at their upper ends, angular braces adaptedto-brace the side frames a ainst the base Vm'einb'ers, bolts securingsaid side frames and braces to the members, said base member'shavingholes adapted to accommodate said bolts When the side frames areadjustedpati) various positions.

3. An apparatus'of the class described comprising, a pair of transversebase memjbers, side frames, secured to said base members, said sideframes having parallel bars at their upper ends a vertical frameconsistingofa pair of uprights connected at their upper ends by acrossbeam, said uprights being secured at their lower extremities to thelower ends of the side frames and at higher points to said parallelbars.

t. An apparatus of the class described comprising, transverse basemembers, side frames secured to the base members, said side framesconsisting of uprights, parallel bars and lowerlongitudinal bars, andinclined bracing .members connecting said uprights With'SELl'd basemembers and longitudinal bars.

5. An apparatus of the class described "comprising, a pair of transversebase anemhejrs, side frames secured to the base 111611 here, said side"frames consisting of uprights. parallel bars and "lower longitudinalbars, inclined 'bracingurnembers connecting said uprights with saidbase-members and longitudinal bars. saidbr-acing members all restingwiththeirlower ends onthe floor.

In testimony'whereof We aiiix our signa- 'tures.
